1 EXPLOSION PROOF Diesel Engines For Hazardous Areas

2 HAZARDOUS AREAS Managing the Risk There is always a risk of a flammable hydrocarbon release in the oil and gas industry. When the release comes into contact with air and an ignition source, an explosion can happen. Cat solutions are designed to help keep these elements apart. The Science of Explosions When the job takes you into a hazardous location, Cat engines are ready. Our complete range of services and engine packages cover both industry standards and Safety is only effectively achieved through a holistic approach to explosion protection. All factors must be considered in conjunction as illustrated here it only takes one weak link to cause an explosion. Strong governance and hazardous area policy Deep safety culture Correctly specified hazardous area equipment Risk assessment and consulting Central control room shutdown Equipment protection inc. rotating equipment Training Area classification Proactive service and support your operation with maximum safety.

3 Diesel Engines in Hazardous Areas Potential ignition sources on unprotected diesel engines include electrical, mechanical, or static sparks, overspeed or flame from inlet or exhaust, and hot surfaces. Flammable gases in the atmosphere can be sucked in through the air intake along with air for combustion. This can result in flashbacks through the inlet, backfires in the exhaust, or engine overspeed. If the engine consumes flammable gas mixed with air and diesel fuel, engine overspeed can occur, which can lead to the engine running out of control. This can result in catastrophic failure of the engine. Another risk is engine misfiring, leading to an explosion further down the exhaust system, which could then ignite the surrounding atmosphere. Various surfaces on a diesel engine can become hot and therefore sources of ignition. These surfaces need to be protected to avoid the danger of explosion. Cat explosion-protection technology was developed to guard against these and many other dangers. Engine Design A typical Cat engine includes features designed to prevent an ignition source causing an explosion in the event of a hydrocarbon release. KEY Air Inlet Flame Arrester with Shut-off Valve Provides shutdown on overspeed Water-cooled Turbocharger and Exhaust Manifold Ensures surface temperature is below 200oC (T3) Exhaust Gas Heat Exchanger Cools the engine exhaust below 200oC (T3) Spark Arrestor Ensures that no sparks or hot particles escape into the atmosphere Radiator The solder-dipped radiator core provides additional cooling capacity Explosion protection also includes: Battery and electrics Charge air pipe Automated shut-off system ECM
